On December 8, 1896, Henry Osborne Havemeyer, who was to be one of the great benefactors of the Metropolitan, sent a letter to Henry G. Marquand, then President, offering to give the Museum a group of fifty-six objects. "Since the Tiffany Glass Co. have been making favrile glass,"' Mr. Havemeyer wrote, "Mr. Louis Tiffany has set aside the finest pieces of their production, which I have acquired...

Humility is key to public value, so courage. For me, this the message of Prebble’s stimulating article. It comes at a good time, when value thinking well-established, theorizing about it differentiates into more or less normative schools thought and empirical research on its way—normal science as one could say. I read Mark’s argument wake-up call take process-oriented level reflect chances risk...

In recent years, several techniques have been proposed for automatically producing line-art illustrations. In this paper a new non photo-realistic rendering scheme for triangulated surfaces is presented. In contrast to prior approaches with parametric surfaces, there is no global parameterization for triangle meshes. So a new approach is made to automatically generate a direction field for the ...

In this paper we show how to extend point-based surface rendering to illustrate object motion. We do this by first extruding the circular points into ellipsoids, which fill the space traced out by the points in motion. Using ellipsoids instead of cylinders achieves a low-passing effect of the motion trail. We then find the screen-space projection of each ellipsoid, which is an ellipse. These ca...

Historical and empirical data have linked artistic creativity to depression and other affective disorders. This study examined how vulnerability to experiencing negative affect, measured with biological products, and intense negative emotions influenced artistic creativity. The authors assessed participants' baseline levels of an adrenal steroid (dehydroepiandrosterone-sulfate, or DHEAS), previ...
